There are many denominations of Christianity based on slight differences that are what Paul calls "disputable matters". We are all free to choose what makes sense to us. But that is not to say that you can stray arbitrarily far from the truth.

The only thing that matters is that we admit we can't meet God's standards and that He had to reach down and do it for us by suffering the consequences of our shortcomings for us.

That's it. All other religions (those made up by humans) continue to insist that there are things we can do to earn our own salvation. These are presumptive, arrogant and by their very nature offensive to God.

So, don't sweat the small stuff that divide us. Focus on the Only Thing that matters.
